SUPPLEMENTARY INFORMATION: On 

October 3, 2023 (88 FR 67929), the NRC 

published a direct final rule amending 

its regulations in part 72 of title 10 of 

the Code of Federal Regulations to the 

TN Americas LLC, Standardized 

NUHOMS® Horizontal Modular Storage 

System for Irradiated Nuclear Fuel 

listing within the ‘‘List of approved 

spent fuel storage casks’’ to include 

Renewed Amendment No. 18 to 

Certificate of Compliance (CoC) No. 

1004. Renewed Amendment No. 18 

amends the certificate of compliance to: 

• provide a 24PTH improved basket 

design (Type 3) using staggered plates 

similar to EOS–37PTH to simplify 

construction, reduce weight, and 

improve fabricability; 

• delete Appendix A inspections, 

tests, and evaluations requirement for 

initial horizontal storage module delta 

temperature measurement with a loaded 

dry shielded canister (DSC); 

• clarify Appendix B technical 

specification (TS) Section 4.3.2 language 

related to transfer casks with liquid 

neutron shields regarding the OS197L 

transfer cask (TC), which is significantly 

different than other TC models; 

• update Appendix C American 

Society of Mechanical Engineers 

(ASME) Code Alternatives Table C–12 

to add code alternative NG–4231.1; 

• clarify in Appendix B TS LCO 3.1.3 

that there is no transfer time limit 

associated with the 24PTH–S–LC DSC, 

consistent with existing updated final 

safety analysis report analysis; 

• incorporate administrative controls 

during short duration independent 

spent fuel storage installation handling 

operations that are unanalyzed for 

tornado hazards in accordance with the 

guidance contained in NRC EGM 22– 

001, ‘‘Enforcement Discretion for 

Noncompliance of Tornado Hazards 

Protection Requirements at Independent 

Spent Fuel Storage Installations’’; and 

• change the horizontal storage 

module concrete, to allow use of 

different cement, which is a blended 

Portland cement meeting the 

requirements of the American Society 

for Testing and Materials C595 standard. 

This amendment also includes an 

editorial correction to the certificate of 

compliance name/address information 

by adding a missing space between 7160 

and Riverwood Drive. 

In the direct final rule, the NRC stated 

that if no significant adverse comments 

were received, the direct final rule 

would become effective on December 

18, 2023. The NRC did not receive any 

comments on the direct final rule. 

Therefore, this direct final rule will 

become effective as scheduled. 

Dated: November 15, 2023.
